Specification of Letters Patent.

Patented Mar. 1s, 1919.

Application filed October 20, 1914. Serial No. 867.570.

To all whom t may concern: Y

Be it known that I, AUGUST J. KREUZ- KAMP, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Bed- Springs,of which the following is a specication.

This invention relates to bed springs, more particularly to that formthereof known as spiral bed springs, in which the spring consists ofsuitable supporting means and spiral springs carried thereby forsupporting the ordinary'stufed mattress, the object of the inventionbeing 'to provide an improved spring of this kind.

I-Ieretofore it has been found practicable to provide only flat bedsprings, that is springs in which the bottomis formed of a fabric ofsome kind, with side-guards, and although it has been highly desirableto make spiral bed .springs with side-guards this has not been foundpracticable for various reasons, among others the diiiiculty ofattaching and the difficulty of maintaining such side-guards in shapeand position, and therefore I believe that Iam the first to provide aside-guard spiral bed spring in which the guards will prevent theshifting, spreading and flattening of a stuffed mattress and maintain itin its boxlike shape, and therefore the object of the presentimprovement is the provision of a bed spring of the class describedhaving side-guards expensively but practically applied, and whichstructure is durable and practicable so that all the advantages of theordinary sideguard flat spring are obtained in the spiral form of bedspring.

In the drawings accompanying and forming part of this specification,Figure 1 is a perspective view of this improved springt; Fig. 2 is aside view thereof; and Fig. 3 is a detail view of the guard partlybroken away. VSimilar characters of reference indicate correspondingpartsy throughout the several figures of the drawings.

The spiral spring supporting means may consist of any suitable.framework 2. In the form shown it consists of a pair of lon- 'gituclinalextending bars 3 shown as of angle which are iniron form connectedcrosswise at their ends by suitable angle iron bars 4, and by a seriesof intermediate bars. Supported by these bars are a series of spiralsprings 5 of any suitable form. The outer row of springs at each side ofthe bed spring is shown connected by a longitudinally extending wire orrod 6 inturned at its ends as at 7 and connected along the inner sidesof certain of the springs. The angle iron bars t are bent upward attheirends as at 8 so as to extend above the spiral springs va predetermineddistance, thus forming guard supporting means or brackets 8', and thesebrackets are connected by braces 9 with the spring supporting means, andthe upturned portions are also suitably braced. In the present instancethe lower ends of the braces 9 at each side of the. bed spring areconnected with the outer longitudinal extending bar. Stretched betweenthe upper ends of the `supporting brackets .is a Asuitable side guard10. In the presentinstance, this guard is formed of fabric, as forinstance a woven wire fabric, and in this form ofguard each end thereofis provided with a binding strip 11 and each end is secured by one ormore, shown as three `in number, coil springs 12 with abracket 8 wherebythe guard is maintained under tension so that it will normally retainits upright position and be returned to its normal position when flexedtherefrom. In the present instance each guard is provided with'alarge'or reinforced upper edge 13 which, in the formshown, consists of aseries of spirally wound wires effective also to assist in maintainingthe side-guard under tension. The lower edge of the guard is preferablyprovided with a longitudinally extending wire 14 thereby reinforcing it,and it is tied at intervals by Vmetal rings to the spiral springconnecting resist any compressive force applied thereto. It will beobserved that in the present im proved structure the supporting bracketsextend above the spiral springs so that the y' guard of whatever formmaybe usedY is located above the tops of whatever forms of so ,tendingwire tied to said springs and a spiral springs that may be used, so thatwhen the stuffed mattressis in position the Y guard willralways be inproper position to prevent' any shifting and flattening and spreadingofthe stulfed mattress, and main- .tain it in its box-like form.

In practice theV height of the guard member may be varied somewhat, butit is usuallyabout three inches high, and therefore extends about thisdistancey above the spiral springs. In other words, by reason of thepresentV construction any compression of the side row ofy spiralsupportingfsprings carries with them the side-guards which, however, byreason of the fact that'these Aside-guards are supported under tension,is

maintained Vin proper position to insure the advantages referred'to.

It will be understood that the various details may bemore or lessmodilied without departing from the spirit or scope ofthe presentimprovement, which broadly con-` sists in the provision of-meanslocated-aboveV the spiral supporting springs for main-Y tainingthe shapeof the stuffed mattress and preventing the spreading and flatteningV andshifting thereof. For instance, it .will bey understood that thesupportingmeans as usedY herein and in the claims may consist of anymeans which supports or connects or ties the several springs into astructure 'whereby it maybe utilizedas a spring mattress. Y n Y Thespiral .bed springs as frequently called, are not infrequently calledbox spr-ings'by .reasonfof the fact that the structure is usuallycovered with somesuitable form of ticking, that is toV say,cthe springsare usually entirely inclosed along the sides, ends and top withticking, while the bottom is usually of some cheaper material and, ofcourse, .when the spring is so covered the guards could likewise becovered-by the ticking also.- Of course, it .will be understood thatthesprirng structure itself may be socovered without covering theside-guards if this is not desired.

I claimv-as'my invention: y v Y 1. A bed vspring comprising. supportingmeans, a series of spiral springs` carried thereby, brackets at eachside extending nected to saidV brackets for preventing a Vstuffedmattress from flattening, spreading and sagging over the lengthwise edgeof theV spring, andl means? connecting said vguard member lwith theouter row of springs, said means consisting Vof a longitudinallyexlongitudinally extending wire yconnected means connecting said wires.

2. A bed spring comprising VsupportingY means, a series lof spiralsprings carried thereby, said supporting means including a pair ofYcross members Y having upturned bracket portions extending above saidspiral springs at the corners ,of the bed spring, a vside-guardstretched under Ytension between said brackets and extending above saidspiral springs for preventing a stued inattres's from-flattening,spreading and Vsagging over the edge of the spring, and braces conynecting .said upstanding brackets with' the spiral spring supportingmeans.
